The Swedish House Mafia is a Swedish house music act consisting of three DJs and producers — axwell, Steve Angello and sebastian ingrosso — that formed in late 2008.

The Swedish House Mafia released their first official single "One" under the name Swedish House Mafia on Beatport on 26 May 2010, where it achieved international success.

Axwell has said the formation of the Swedish House Mafia occurred when he moved to Stockholm, he later met Steve Angello through Ingrosso. "The name is just a random thought.", as described by Steve Angello, it occurred outside a 7 Eleven late at night while drinking coffee.

In 2010 the Swedish House Mafia signed a record deal with EMI and a publishing deal with Universal Music Publishing. In Australia they are signed to Ministry of Sound Australia & EMI Australia.
